大多数生物大分子和基团的振动或者转动能级处于太赫兹频段，而其生物活性在水溶液中才能表现出来，由于水对太赫兹波的强烈吸收，从而限制了太赫兹技术的推广和应用。为了研究水溶液中生物样品的反应、变化等动态特性，将太赫兹技术和微流控技术相结合，分别研究了微流控芯片上微流控沟道的尺寸，微流控芯片的材料及其制作流程，最后用去离子水对该芯片进行了初步测试，证明了该太赫兹微流控芯片的可行性。

Most of the vibrational or rotational energy levels of biological macromolecules and groups are in terahertz band, and their biological activities can only be shown in aqueous solution. The strong absorption of terahertz waves by water limits the popularization and application of terahertz technology. In order to study the dynamic characteristics of the reaction and change of biological samples in aqueous solution, terahertz technology and microfluidic technology are combined to study the size of microfluidic channels on microfluidic chips, the materials and fabrication process of microfluidic chips. Finally, the chip is tested by deionized water, which proves the feasibility of the terahertz microfluidic chip.
